Cinematography Electronics
The Cinematography Electronics /i Lens Display Unit interfaces the Cooke S4/i lens system with their popular CineTape Measure System, and adds lens data previously not available: actual measured subject distance. The focus puller now knows where the subject falls within the depth-of-field for the particular lens being used. This data is continuously updated and displayed for real time information. Pre-adjustment or pre-setting is never necessary. In fact, you can choose to display hyper focal distance, subject distance, focus marks, the entrance pupil position and angle-of-view, which is information that could save hours of prep time before a motion control shoot.
CMotion
With /i equipped CMotion lens control systems, your zoom controller can communicate directly with your /i equipped lens giving you iris, zoom and focus positions resulting in faster set-ups and more accurate control.
Codex

Mark Roberts Motion Control
The /i Technology is incorporated into some of the Mark Roberts Motion Control remote and repeatable pan-tilt heads, such as the Ulti-head, so that while the cameraman is controlling the head, including pan, tilt, zoom and focus, the system can also accurately record the calibrated lens data using the /i Technology. This data can then be fed through to post production to more easily add any computer graphic elements. Camera and lens motion data is often required for post production and the /i metadata saves the cameraman or operator, time in getting correctly calibrated data for the lens motion. The Ulti-head can be used on its own or with the larger MRMC products such as the Modula and the Talos rigs. See Mark Roberts Motion Control for more information about their products for film and broadcast applications, including the Academy Award winning Milo, Cyclops, Talos, Modula and Ulti-head.

Optitek will translate Canon lens encoder information into Cooke /i Technology commands so lens data (focus, aperture, lens type, etc.) can be displayed in camera view finder and recorded as metadata in video files. Camera commands to lens will also be translated into Canon protocol.
Ovide
Smart Assist is an advanced Video Playback system for digital cinema, recording high quality video from cameras in ProRes format and playing it back in the video village - even streaming to iPhones and iPads. Metadata is a core feature of the systems, retrieving manual metadata from users (scene, shot, take, rating, notes), and automatic metadata (camera settings, lens settings) for every frame. Smart Assist will read lens’ type, serial number, focus, iris and zoom for every frame and store it for precise frame retake, vfx export and 3D vfx realtime preview; follow dolly tracks, motion control systems and lens settings creating appropriate live background plates matching camera and lens changes.

The Foundry
The Foundry plans to incorporate /i Techology capability into future Nuke software releases. It will have an in-built 3D camera tracker, to which the user can provide additional hints and constraints about the shoot to recreate the camera –- for example, which lens was used. In addition, shoot lens distortion grids with different focal lengths, and the /i data will give you an accurate focal length. Use a lens tool to undistort the plate, then use the camera tracker within Nuke to reapply this to the footage. Having the /i data will make the tracking process much simpler, particularly since lens distortion changes with the zoom.
